Bodyslide armor losing shoulder parts?

[c6222848]

Hey everyone, 

 

So i download the Banded Iron bikini ver.2 on nexusmod :http://www.nexusmods.com/skyrim/mods/69631/?

And i try to use Bodyslide outfitstudio to merge the parts of it into a single armor. then i run bodyslide and create the nif files.(i can see the shoulder part  in the preview and nif file.)

But when i go in to game and get that armor, i can only see the knee armor ， the shoulder and spine part are missing?

what did i do wrong?
